Description

The present invention relates to a thrombosis prevention cushion.

In recent years, the risk of deep vein thrombosis, which occurs during and after an aircraft trip, which is called economy class syndrome, has been pointed out. When sitting without moving the lower limbs for a long time, blood clots form in the veins in the back of the thighs, and some of them move to the lungs due to blood flow and pinch the blood vessels in the lungs. As countermeasures, aggressive foot movements are recommended while seated, and air cushions are also commercially available as auxiliary equipment, but can be classified into the following two categories.

The first is a cushion for stepping. (For example, refer nonpatent literature 1.). The second is a cushion that hangs on the lunch table of the vehicle and rests on the foot. (See, for example, Patent Document 1 and Non-Patent Document 2.)

Hereinafter, a conventional cushion will be described.
FIG. 17 is the first one described above, which can be used to move the foot alternately and step on the cushion, and seems to have a certain effect, but since there is no protrusion, the effect of improving blood circulation by acupoint stimulation is sufficient. In addition, there was a drawback that it was easy to become monotonous at the same time, and it was not possible to hang the foot like the second one.

FIG. 18 and FIG. 19 are the above-mentioned second ones, which can be hung on the seat seat and put a foot on, but there is a drawback that the stepping motion cannot be performed as in the first one. In FIG. 19, the cushion main body is put in a cover case and hung for use.
Product name "Athletic meet for feet" Product name "Multi Cushion" JP2001-149182

In order to eliminate the above drawbacks, the present invention has both a stepping motion with a single cushion and the function of hanging and placing a foot, and at the same time, improves blood circulation by acupuncture stimulation and produces a thrombosis prevention cushion. It is the purpose.

  Using a vinyl chloride sheet as the material, drill a plurality of holes in the top sheet of the cushion, insert a plurality of protrusions and weld them, and weld the gusset to the middle and bottom sheets with small holes through which air enters and exits To do.

Moreover, in order to suspend it from the lunch table of the vehicle, a side portion having a hole through which the string can be attached and detached is provided, and a hard plastic sheet is inserted into the periphery of the hole to be strengthened.

Further, an air injecting valve and a cover device with a hook-and-loop fastener that protects the valve are welded to the back of the cushion, and the periphery of the cushion body is welded. With the above configuration, one product has both functions, and at the same time, blood circulation is improved by acupuncture stimulation with protrusions, and a synergistic effect can be obtained for thrombosis prevention.

The main effects of the present invention are as follows.
First, sit in a vehicle, place the proposed cushion on the floor, take off your footwear and perform the following exercises.
Start from either the left or right foot of the left and right sides of the protrusion. Then the air is compressed and moves to the other side. So step on your foot full of air. This exercise is performed rhythmically in conjunction with left and right alternately.
The following effects can be obtained by the above exercise.

Legs have been said to be a microcosm of the human body from a long time ago, and are closely related to the internal structure of the body, but when the points on the sole of the foot, i.e., reflexes, are stimulated by the protrusions on the cushion of the present invention, the stimulation is transmitted to the brain Blood and lymph circulation is improved.

Furthermore, the above-mentioned exercise actively works the muscles of the lower limbs of the human body, and the stimulation / exercise applied to the muscles enhances the muscular strength, promotes energy consumption, improves metabolism, and improves blood flow. When I actually experimented, I was able to experience the movement of many muscles such as the rectus femoris located on the front of the human body and the soleus and biceps femoris located on the back.

Secondly, a string with an attached eggplant or S-shaped can is attached to the holes on both sides of the cushion.

Suspend on the lunch table of the vehicle, put your foot on it and relax, and at the same time prevent Mukumi on your foot.
Although thrombosis is likely to occur when the posture is the same for a long time, using a strap that can adjust the length of the strap and freely changing the position of the foot can help prevent thrombosis.

As described above, the present invention has both the conventional stepping motion and the function of hanging and placing the foot, and further, the effect of improving blood circulation by stimulating the acupuncture points by the protrusions can be realized with a single cushion. In addition, it is easy to make monotonous exercises, and exercises that exercise positive feelings to stimulate acupoints by protrusions work closely in conjunction with muscle movements of the lower limbs, improving blood circulation. . In addition, it is a psychologically and physically effective method that has a synergistic effect on the prevention of blood clots in the aircraft and in the vehicle, where it sits for a long time, such as removing the lumps of the foot by hanging it on the lunch table. The present invention is a universal cushion that can be used comfortably by not only preventing thrombosis but also applying it to the waist, back, and neck while freely adjusting the amount of air.

Hereinafter, embodiments of the present invention will be described with reference to FIGS.

Three vinyl chloride sheets 1 having the shape shown in FIG. 2 are produced.

The first sheet is used as the uppermost sheet 2 of the cushion body as shown in FIGS. 1, 3, 10, 11, and 12, and a plurality of holes 3 are formed as shown in FIG. A plurality of protrusions 4 in FIG. 5 are inserted from below the uppermost sheet 2 and protruded from the surface, and the protrusion base 5 and the joining portion 6 on the back surface of the uppermost sheet 2 are welded at a high frequency as shown by the hatched portion in FIG. . Note that the protrusions are hollow as shown in FIG.

The second sheet is used as the lowermost sheet 7 of the cushion body as shown in FIGS. 1, 8, 10, 11, and 13, and protects the air injection valve 8 and the valve as shown in FIG. The loop surface 9a and the hook surface 9b of the cover device 9 with a hook-and-loop fastener are arranged and welded at high frequency. When installing a cover device that protects the valve, the product may be placed on the floor or placed on the floor, and in consideration of hygiene in order to allow air to enter the mouth.

The third sheet is used as an intermediate sheet 10 between the uppermost sheet 2 and the lowermost sheet 7 as shown in FIGS. 10 and 11, and small holes 11 are opened on both the left and right sides as shown in FIG.

The gusset 12 is welded to the intermediate sheet 10 and the lowermost first sheet 7 at a high frequency as shown in FIGS. The reason for using the intermediate sheet 10 is that if only two sheets of the highest sheet and the lowermost sheet are used and gussets are attached, the gussets of the uppermost sheet and the lowermost sheet are removed when air is introduced. It is not a situation where the attached part is pulled and collapsed and a protrusion is attached to this. Therefore, by using an intermediate seat, the outer appearance is not visible when air is introduced, but the portion to which the gusset of the intermediate seat is attached is formed with a dent 13, and the gusset suppresses the cushion to a constant thickness. At the same time, an air chamber 14 through which air enters and exits from the small hole 11 between the uppermost sheet and the intermediate sheet is formed, the uppermost sheet becomes a flat surface, and the protrusions 4 are attached to the shape as shown in FIGS. Become.

As shown in FIG. 14, a side portion 16 having a hole 15 for attaching and detaching a string is provided, and a grommet 17 is attached. In addition, since the sheet | seat circumference part which attaches eyelets attaches a string to an eggplant or S character can, and pulls, there exists a possibility that a strong tension may be applied and it may be damaged. In order to prevent this, a hard plastic sheet is used and sandwiched between the intermediate sheet 10 and the uppermost sheet 2 or the lowermost sheet 7, and finally the circumferential portion 18 indicated by the oblique lines with the three sheets and the hard plastic sheet. As shown in Fig. 4, the integrated reinforcing sheet is manufactured by welding at high frequency.

The peripheral part 19 of the three sheets of the uppermost sheet 2, the intermediate part sheet 10, and the lowermost sheet 7, and the boundary part 19 between the side part 16 having the hole 15 and the peripheral part of the cushion main body for introducing air as shown in FIG. Is welded at high frequency.

As shown in FIG. 1, the string 22 attached with the eggplant 20 and the string stopper 21 for adjusting the length of the string can be attached to and detached from the cushion.

In order to improve the feel of the cushion, the uppermost sheet 2 and the lowermost sheet 7 can use a flocked vinyl chloride sheet, and the intermediate sheet 10 can use a normal vinyl chloride sheet.

In the present embodiment configured as described above, when air is introduced, the shape becomes the shape of FIG. 1, FIG. 10, FIG. 11, FIG. 12 and FIG. Moreover, it becomes a thrombosis prevention cushion which can be hung on a lunch table as shown in FIG. 16 and FIG.
